用冲击波处理用共沉淀法制备的氧化铁和氧化镍混合物，合成了铁酸镍，用XRD；TEM及电子衍射法对合成产物进行了表征合成产物基本为具有较高的磁化强度的纳米级铁酸镍，主要原因可能是纳米前体有较高的的反应活性，冲击波作用时问极短冲击波处理可能成为制备复合金属氧化物纳米粉体的新方法
The mixture of iron oxide and nickel oxide prepared by coprecipitation method was treated by shock wave to synthesize nickel ferrite. The synthesized products were characterized by XRD, TEM and electron diffraction. The synthesized products were basically nanoscale iron with higher magnetization Nickel acid, the main reason may be that the nano-precursors have higher reactivity, shock wave effect when asked very short shock wave processing may become a new method for the preparation of composite metal oxide nanopowders
